SHEET PILING.

Application `filed January 29, 1927. ySerial No. 164,504.

This invention relates to sheet piling of c the interlocking type and,specifically, con- I am aware.

sists of sheet piling composed of identical trough-shaped elements, thelongitudinal edges of which are so shaped that theelements can beinterlocked and separated laterally, instead of being threaded togetherlongitudinally as usual, and that the elements can be alternatelyreversed to face in opposite directions, if desired.

This new form of sheet piling, usually made of rolled steel sections,possesses several material advantages not `found in prior forms ofinterlocking sheet piling, as far as These advantages are due to thefollowing features of its construction: l, the trough shape of theelements, which gives the greatest rigidity possible for a givenamountof metal; 2, thepeculiar shape of the interlocking edges, whichpermits theL lateral engagement and separation of the elements, and alsothe reversal of alternate elements; 3, the shape of the interlockingedge having the socket for the reception of ytheT head edge of theadjoining element,

whereby the projecting lip, which has to be bent inwardly subsequentlyto thev rolling of the section, can be made much shorter thanheretofore, which facilitates the rolling operation and the bendingoperation and renders said lip muc-h less likely to be distorted by hardmaterial in the driving of the pile.

I am aware that sheet piling capable of being interlocked laterally hasheretofore been proposed, but in no instance of which I am aware, canalternate sections bey reversed in position and still be laterallyinterloclzed and separated. The alternately reversed position of theelements is very desirable'because it imparts the greatest possiblestiffness and strength to the piling wa l.

The invention is illustrated in the accompanying drawing, in which Fig.l is a crosssectional view of a piling wall composed of the in'iprovedelements arranged in reversed position; Fig. 2 is a partial elevationVof ythe same and Fig. 3 is a cross section like Fig. 1 but with theelements not reversed.

In these views, the pilingwall is composed of identical trough-shapedelements or Sections 1, each ofwhich is anged along its longitudinaledges, one fiange carrying the male T head 2 and the other the femalesocket head 3. These sections are rolled to inished shape, with theexception of the lip 4, which is subsequently bent over, as shown,

to complete the socket and retain the T head of the adjoining sectionwhile permitting its being laterally engaged andV disengaged. Said lipis relatively short, so that it 'can be formed in the rolling operationwithout the necessity of a deep groove in the rolls. The T and socketheads are so formed, as will be apparent from the drawing, that all thesections may liey on the same side of the vertical plane passing throughthe interlocking edges, or that alternate sections may vlie on oppositesides of said plane, as shown in Fig. l. As beforestated, the alternatearrangement is preferable, on acount of the great rigidity thereby`robtained but, where the available space is insufficient .for thereversed arrangement, the sections may be interlocked in the samerelative position, as shown .in Fig. 3. I

Piling thus constructed is, to a `certain degree, fiexible, theinterlocking edges permitting some angularity between'the sections. Itis economical to manufacture, easy to install and disassemble, and givesthev greatest posible rigidity for the weight of metal use Having thusdescribed my invention, what I claim is: l. A retaining wall of Asheetpiling, comprising a plurality of identical troughshaped rolledsections, each section having a rounded Tv head on one edge and an openmouth socket on the other edge, whereby the lsections can be engagedlaterally and the front and back depth'of the wall can be doubled byreversing alternate sections.

2. A sheet piling unit consisting vof a channel section flanged on itsedges, one of said flanges carrying a head of rounded T shape and theother flange carrying a projecting claw and an extended lip, the latterbeing bent over to form, withA said claw, a socket in which the T headof an adjacent sectioncan be engaged by lat-eral entrance, whether saidadjacent section is in the same relative position as the first sectionor is reversed relatively to the same.A

In testimony whereof I have hereunto set my hand.
